The complete solution for your iOS app development needs,
from idea conception to release management.

Conception

Whether it’s brainstorming new ideas or assessing the viability of existing product choices, I can help you see the broader picture. We can talk device capabilities, app ecosystem ideas, user engagement, product design, and the user experience as a whole.

Prototyping

Best way to see how a product feels in the hands of the end user? Prototype it. I can help you mock-up variations of a feature quickly so you can pick the one that feels the best before ever embarking on developing production-quality code.

Architecture

Solid architecture decides your product stability and code longevity, and those translate to user retention and development costs. I can help you modularize your code, separate logical components from their visual counterparts, and distill core frameworks for reuse within your app ecosystem.

Development

With over 15 years of professional development experience, I can help you produce quality code quickly, thinking of edge cases, potential race conditions, and common pitfalls from the get go. Good code design and solid development techniques can help significantly minimize bug tails and shorten development cycles.

Release

Having released apps on the Apple App Store many times over, I can usher you through the process, help you correctly manage timelines and schedules, and minimize the potential of your app being rejected last minute.

Mentoring

Whether you’re managing a junior or a senior team that is new to iOS, I can fill your gaps in know-how with hands-on examples, suggestions, code reviews, design reviews, and comments that are appropriate to the skill levels of individual team members.

When we needed some help with some custom animations that were difficult to pull off but that were a very core part of using our app, we were fortunate enough to get Juraj's help. The quality of his games is no fluke. This man possesses amazing creativity, has astounding attention to detail, knows how to expertly engineer software, and has the ability to make things feel right.Juraj listened to what we wanted to try to create and iteratively worked with us to make it real.I would love to collaborate with him again on any number of projects and honestly can't recommend him enough.

Russell Taga

CTO, Coin

Rockstar team player engineer. Juraj has helped out on our iOS projects a couple times now and it is always a pleasure. He clearly communicates what he can deliver in what time and then makes it happen. He works well with the rest our team, using his expertise to provide code review feedback and mentorship to other engineers.

In other words if Juraj was an uber driver he would pick you up in a GT-R, suggest a better color tie to match your suit, find a fast but safe way around downtown traffic, and leave you at your destination with a water bottle in hand - 5/5 stars

Andy Mast

Dev Manager, Deako

Juraj is a skilled, meticulous and thoughtful iOS developer who worked with us in a key transition for Siren. He is strategic and detail-oriented in his coding practice, but also has the ability to step away and analyze the results from a user perspective, and not simply get buried in lines of code. He has a flair for design and offers up-to-date knowledge of UX / UI. Juraj is independent and responsible, and offers both maturity and integrity as a developer.

It was wonderful working with him.

Susie Lee

CEO, Siren

Juraj joined us at UIEvolution and immediately had in impact on a project that was chaotic, staffed by a junior team and running under impossibly tight deadlines.

Juraj did a fantastic job bringing sanity and senior technical guidance to the team. He is collaborative by nature, a strong communicator, and best of all has rock-star technical talent. He left a lasting impact not only on the project but also on the people he worked with.

VP of Automotive, UIEvolution

I’m Juraj and I’ve been writing iOS apps since the first days of the iPhone, when I left Microsoft to take a “little break”. Over the years, I’ve published well over a dozen apps of my own and helped at least as many other companies, from startups to large corporations, to publish theirs.

My own apps have received countless accolades, from the coveted Apple Design Award to praises from CNN and The New York Times.

Building upon a CS degree from Harvard and 15 years of development experience in C, C++, Java, C#, Objective-C and Swift, I bring practical know-how that enables my clients to author the right app, the first time. I can be equally effective working independently as well as plugging myself into an existing team infrastructure. Companies of various sizes have used my skills to simplify and modularize their code, rapidly prototype ideas for their v2 products, and set a solid direction for their app’s internal architecture and external functionality.

Over the years, I’ve witnesses development strategies that worked and development strategies that failed. I help my clients take the guess work out of the equation and offer suggestions that help maximize their potential for success, given their resources and needs.
